| S/W. Wst. Car Radio Sets. Hs{Lord Ernest Hives - Chair}/Wst.8/MA21.5.35. r6153 WST Cx{Major Len W. Cox - Advertising Manager}17/KW27.5.35. I spoke to Sg{Arthur F. Sidgreaves - MD} about this, and he was a little puzzled to know what to think in view of the fact that he understood from Dodds that on SpectreCodename for Phantom III 3 the Ekco set made a lot of noise when the car was stationary with the engine running, due I believe to the absence of suppressors. I must say that on my Philco set on 9-RY I get no interference whatever from the engine, but then I have suppressors fitted. Perhaps you would let me hear further from you re this, as whilst Sg{Arthur F. Sidgreaves - MD} is not particularly pleased with the wireless set on his own car, he does not see any point in changing if the others are also subject to unpleasant defects. Cx.{Major Len W.
